Side length a, see Make an expression for finding the perimeter and area of a square. Finding the values of the expressions if a = 36.

We know that a square is a quadrangle whose opposite sides are equal.

The sum of all its sides (perimeter) is calculated by the formula:

P = 4a.

And the area of such a figure corresponds to:

S = a².

According to the condition of the task, a = 36 cm.

Let’s find the values:

P = 4 * 36 = 144 cm.

S = 36² = 1296 cm².
